terminals. If a humidifier rated at greater than one amp is connected to this terminal, it is necessary to use an external relay. See Figure 54 for control board configuration. This terminal is energized in the heating mode when the combustion air inducer is operating.

Install the room thermostat according to the instructions provided with the thermostat. See Figure 51 for thermostat designations. If the furnace is being matched with a help pump, refer to the FM21 installation instruction or appropriate dual fuel thermostat instructions.

Indoor Blower Speeds

1.When the thermostat is set to “FAN ON”, the indoor blower will run continuously on the heating speed when there is no cooling or heating demand.

2.When the furnace is running in the heating mode, the indoor blower will run on the heating speed.

3.When there is a cooling demand, the indoor blower will run on the cooling speed.

Generator Use - Voltage Requirements

•The furnace requires 120 volts ± 10% (Range: 180 volts to 132 volts)

•The furnace operates at 60 Hz ± 5% (Range: 57 Hz to 63 Hz)

•The furnace integrated control requires both polarity and proper ground. Both polarity and proper grounding should be checked before attempting to operate the furnace on either permanent or temporary power.

•Generator should have a wave form distortion of less than 5% RHD
